I’m using the Dawn theme, and I have an issue where clicking the “quick Add to Cart” button on my product grid section shows a “Sold Out” message, even though the products are in stock.
It is working fine on product pages.
Anyways – your problem: it’s not “Sold out”. Theme simply says “Sold out” when it was unable to add to cart. Actual reason is “Variant can only be purchased with a selling plan.”
Subscription app needs to be configured to properly work with these – https://appstle.com/faq/ :
Yes! Our subscription widget can be integrated to your homepage/collection pages. The core need for the integration, is to have the ADD TO CART button enabled for the products in the product page. Once this is availabel, please contact our team (available 24/7/365). We will do a quick manual addition of script from our end, and you will be all set.
